The short answer
Compare the purchase price with the monthly payment multiplied by every month you are committed to, plus any fees and buyout. Then check what kind of contract it is: a rental you can cancel, a lease you cannot, or a lease that is really a purchase. Under UCC 2A-407, a lessee's promises in a non-consumer finance lease become irrevocable once the goods are accepted. On tax, IRS Publication 946 says you generally cannot depreciate property you lease from someone else, and Publication 334 covers deducting rent and small equipment purchases. This is general information, not legal or tax advice (September 17, 2026).
Add up the whole commitment
The monthly figure is not the price. For each option, multiply the payment by the months you cannot get out of, then add set-up fees, insurance or protection-plan charges, taxes, and any buyout or return shipping at the end. For a cancellable rental, work out the cost for the period you expect to use it and check the notice period. Illustrative example only, with made-up round numbers: a terminal priced at $400 to buy; a cancellable rental at $20 a month is $720 over 36 months if kept that long; a 48-month lease at $70 a month is $3,360. The comparison changes if you would stop renting after a season.
Rental, finance lease or disguised sale
Contract names vary, so read the terms. UCC 2A-103 defines a finance lease as one where the lessor does not select, manufacture or supply the goods, acquires them in connection with the lease, and meets one of several disclosure conditions about the supply contract. UCC 2A-407 says that in a finance lease that is not a consumer lease, the lessee's promises become irrevocable and independent when the lessee accepts the goods, and are not subject to cancellation without the lessor's consent. UCC 1-203 says a lease the lessee cannot terminate creates a security interest (in effect, a financed sale) if, for example, the lessee can become the owner for no or nominal additional consideration or the term covers the goods' remaining economic life. Our non-cancellable lease guide covers the enforcement history.
What the IRS says about owning and leasing
Publication 946 (2025) says you can depreciate leased property only if you keep the incidents of ownership, such as legal title, the legal obligation to pay for the property and the risk of loss, so a business leasing equipment from someone else generally cannot depreciate it. It lists the section 179 expense deduction limits as $2,500,000 for tax years beginning in 2025, reduced when section 179 property placed in service exceeds $4,000,000, and $2,560,000 for 2026 with a $4,090,000 threshold. Publication 334 (2025) says you can deduct rent for business property you do not own, but not if you have or will receive equity in or title to the property. It also describes a de minimis safe harbor election that lets businesses without an applicable financial statement deduct tangible property costs up to $2,500 per item or invoice ($5,000 with one).
When each option fits
Buying suits a business that expects to keep the same processor and hardware for years and can pay upfront; check that the terminal is not locked to one processor. A cancellable rental suits a new or seasonal business, a trial of a new format, or anyone expecting to change providers, as long as the cancellation terms are in writing. A multi-year lease needs a specific reason, such as financing a large multi-station installation you have priced against buying, and a clear answer on what happens at the end of the term.
Questions to ask before signing
Can I cancel, with how much notice, and what does it cost? Who owns the terminal at the end, and is there a buyout? Is the lease with my processor or a separate leasing company? Does the lease continue if I change processors or close the business? Will the terminal work with another processor? Get each answer in the written contract. This is general information, not legal advice (September 17, 2026).
